Practice report: Aug. 22

TUSCALOOSA, Ala. -- The Thomas-Drew Practice Fields got a little more crowded on Wednesday afternoon as the Crimson Tide welcomed a number of walk-ons to the field for the first time this summer.

It is the first week of school at the University of Alabama and the first opportunity for coach Nick Saban and staff to expand the roster.

Here are some notes and observations from the media viewing period of practice:

Amari Cooper spent a second straight day in a black no-contact jersey on the training bike. The standout true freshman wore a protective boot on his left foot.

Wide reciever Kenny Bell continues to work with the third group during drills. The junior has been dealing with some minor "nagging" injuries, according to Saban. He wore a sleeve on his right knee. Fellow wideout DeAndrew White wore a sleeve on his left knee but did not appear to be slowed.
